This sounds like the upgrade has somehow managed to leave flash-kernel in place, and *not* install piboot-try, which is the replacement for it on Raspberry Pis in resolute (and which should cause the removal of flash-kernel by its installation as it "breaks, replaces, provides" flash-kernel).
Can you check "apt policy piboot-try"? My guess is this will indicate it is *not* installed. If so, try "sudo apt install piboot-try" -- this *should* result in the replacement and removal of flash-kernel (and possibly flash-kernel- piboot as well, although that may hang around as an empty transitional package). After this "sudo flash-kernel" should work (now provided by piboot-try), as should "sudo apt -f install" to finish the upgrade. I'd be very interested to see the full dist-upgrade log in this case, as this is one upgrade that I'm particularly concerned about in the resolute upgrade (I'd already tested it successfully with two questing installs here, but evidently there's something I've missed!). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2147213 Title: [resolute] Unsupported platform 'Raspberry Pi 4 Model B Rev 1.2'.
